Instructions for Use
Power Supply:
- Ensure the supply voltage (Vcc) is set to 5.0V.
- Connect the ground (GND) pin to a stable ground reference.
Addressing:
- Apply the address signals to the address pins (A0-A17) before the falling edge of the Write Enable (WE) or Output Enable (OE) signal.
- Maintain the address signals stable during the access time (tAA).
Data Input:
- For write operations, apply the data to the data input pins (D0-D15) before the falling edge of the Write Enable (WE) signal.
- Ensure the data is held stable for at least the data hold time (tDH) after the falling edge of WE.
Data Output:
- For read operations, the output enable (OE) signal should be pulled low to enable data output.
- The data will be valid on the data output pins (D0-D15) after the output enable delay (tOE).
Control Signals:
- The Write Enable (WE) and Output Enable (OE) signals control the read and write operations.
- Ensure that the control signals are properly synchronized with the clock or timing requirements of your system.
Power Management:
- To reduce power consumption, use the standby mode by keeping the WE and OE signals high when not in use.
- Monitor the standby current (ISB) to ensure it remains within the specified range.
Temperature Considerations:
- Operate the device within the specified operating temperature range (0 to 70°C) to ensure reliable performance.
- Store the device within the storage temperature range (-65 to 150°C) to prevent damage.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Follow proper ESD (Electrostatic Discharge) precautions during handling and installation.
